Triumph or disaster? After Daybreak brilliantly investigates the emergency operation following the British liberation of Belsen.

When British troops entered Bergen-Belsen concentration camp in April 1945, they uncovered scenes of horror and depravity that shocked the world. But they also confronted a terrible challenge - inside the camp were some 60,000 people, suffering from typhus, starvation and dysentery, who would die unless they received immediate medical attention.

After Daybreak is the story of the army stretcher-bearers and ambulance drivers, medical students and relief workers who attempted to save the inmates of Belsen - with the war still raging and only the most primitive drugs and facilities available.

Drawing on their diaries and letters, Ben Shephard reconstructs events at Belsen in the spring of 1945 - from the first horror of its discovery, through the agonising process of trying to save the survivors. In doing so he addresses the question of whether we should regard the relief of the camp as an epic of medical heroism - as the British believed - or see the failure to plan for Belsen and the undoubted mistakes that were made there as further evidence of Allied indifference to the fate of Europe's Jews - as some historians now argue. The result is a powerful and dramatic narrative, full of extraordinary incidents and characters, and an important contribution to medical history.
